A novel polyoxometalate cluster decorated with the directly coordinated organonitrogen ligands: [As(phen)]2[As2Mo2O14]

A novel organic–inorganic molybdenum arsenate compound with chain structure, [As(phen)]2[As2Mo2O14] (phen = 1,10′-phenanthroline) 1, has been synthesized by the hydrothermal reaction and structurally characterized. Compound 1 represents the first example which contains an unusual 1D {As/Mo/O} chain with the phen ligands directly coordinated to the As atoms. Furthermore, a two-dimensional supramolecule layer is formed by π–π stacking interactions of the phen groups between adjacent chains. The electrochemical behavior of 1 modified CPE (1-CPE) has been also studied.
